Modern computer systems, such as servers, may have one or more cores. Each core may have a variety of supporting resources in communication and available to it. This may include memory subsystems that may include main memory, cache, and memory controllers and buffers. The memory subsystems may be one place where the computer holds current programs and data that are in use by the cores. In computer systems with more than one core, a variety of memory subsystems may be used some shared between cores others assigned or structured to support a single core.
